+# TODO
+We can make further improvements and add additional features.
+
+- [ ] Utilize ensemble learning on LSTM model
+- [ ] Use different historical stock price dataset sources other than Yahoo Finance API
+- [ ] Use other time-series model to predict the stock price other than ARIMA (e.g. Stochastic Volatility Model)
+- [ ] Add additive decomposition function to compare with the multiplicative decomposition
+- [ ] Construct other portfolio for evaluation (e.g. Markowitz’s mean-variance portfolio)
+- [ ] Utilize Robust Optimization to get the covariance matrix of the stock log returns
+- [ ] Add other risk distribution strategy to get the budget
+- [ ] Use other risk measures for the risk parity portfolio (e.g. Conditional Value-at-Risk (CVaR))
